Russula. Spores granular, 10 mk. Q. Name consobrinus, cousin. Distantly related 



to neighbouring species. Fr. Monogr. ii. /. 195. Hym. Eur. p. 447. B. & Br. 

 n. 1676. S. Mycol. Scot. n. 599. 



* R. sororia Larbr. Pileus convex then plane or depressed, 

 striate, at the margin. Gills somewhat distant, connected by 

 veins. 



The habit and colour are the same, but it differs by many marks. Stem 

 white. Many of the gills dimidiate, but scarcely forked. Name soror, a 

 sister. From its relation to R. consobrina. In fir woods. North Wooton.

25. R. fcetens Fr. Pileus 10-12.5 cent (4-5 i n -) 



broad, dingy yellow, often becoming pale, thinly fleshy, at first 

 bullate, then expanded and depressed, covered with a pellicle 

 which is adnate, not separable, and viscid in wet weather, margin 

 broadly membranaceous, at the first bent inwards with ribs which 

 are at length tubercular ; flesh thin, rigid- fragile, pallid. Stem 

 5 cent. (2 in.) and more long, 1-2.5 cent. (/4.-1 in.) thick, stout, 

 stuffed then hollow, whitish. Gills adnexed, crowded, connected 

 by veins, with very many dimidiate and forked ones intermixed, 

 whitish, at the first exuding watery drops. 



Fcetid. Taste acrid. Very rigid, most distinct from all others in its very 

 heavy empyreiimatic. odour. In very dry weather the odour is often obsolete. 

 The margin is more broadly membranaceous and hence marked with longer 

 furrows than in any other species. It differs from all the preceding ones in 

 the gills at the first exuding watery drops. The gills become obsoletely 

 light yellow, and dingy when bruised. 



In woods, c. Very common. July-Sept. 



Stem ruggedly hollow within as if eaten by snails. M.J.B. A very coarse 

 and easily recognised species. Reckoned poisonous, though eaten by slugs. 

 Spores minutely echinulate, almost globular, 8 mk. W.G.S. Name fcetens,

26. R. subfoetens Smith. Pileus bullate, somewhat viscid, 

 disc fleshy, margin somewhat membranaceous. Stem not stout. 

 Gills thick, distant, branched. 



Odour somewhat disagreeable, taste slightly acrid. Smaller than R. fattens, 

 stem not so stout, margin different. This is the plant referred to by Fries 

 Syst. Myc. i. p. 58. as a var. of R. fragilis.
